The swimming pool at the Marina Centre in Great Yarmouth has undergone a major refurbishment, headed up by specialist water leisure engineers Pool Maintenance.
The authority-owned seafront facility on Marine Parade, which is run by the Great Yarmouth Sport and Leisure Trust, hadn’t been renovated since it opened over 35 years ago.
The entire existing filtration plant that had been installed in 1980 was decommissioned and removed, including three 8ft vertical steel filters and ancillary equipment such as 12” steel and PVC pipework, pumps, strainers, heat exchangers, chemical dosing and control panels.
It was replaced with a fully automated plant, featuring four new 3.2m GRP horizontal filters, new pumps, inverters, UV treatment, chemical dosing, PLC controlled auto backwashing facility and new heat exchanger and valves.
Pool Maintenance was appointed as the main contractor, Bowers and Barr electricians rewired the plantroom and Stimpsons Heating Engineers replaced all the boiler pipework, pumps and put in all new control systems.
“The aim of the project was to greatly improve the water quality and filtration rates, which we achieved and completed four days ahead of schedule,” explains Paul Styler of Pool Maintenance.
“Like all new challenges you can’t predict where or when the issues will arise. In this case, the ducting on the AHU units supported on a mezzanine floor above the filters had deteriorated and large holes had appeared. When we started to burn out the filters the fumes went through into the indoor bowls hall, which meant we had to burn the filters out through the nights.
“Positioning the horizontal filters meant we had to remove vertical support girders to the mezzanine, put in temporary supports until filters were in place, then redesign and install the mezzanine support system.”
